Abstract

The nonradiative transition dynamics between the excited ⁴T₂ state and the metastable ²E storage state of the trivalent chromium ion in emerald is investigated using the picosecond excite-and-probe absorption technique. An intra-⁴T₂ state vibrational relaxation time of 23 ps, and a ⁴T₂→²E electronic relaxation time of 20 ps are obtained. The thermal repopulation rate of the ⁴T₂ state from the metastable ²E level is ~9.0×10⁹ s^-1.
